@Louis-DT-WR A twin disc set-up sweettttttt!!!!
-
@NINJA yes indeed, it's the R6 front wheel
-
@Louis-DT-WR Are you building this for off-road on on-road use, or a bit of both?
-
Together they look like this.
Brat style
-
Frame is now powdered
New tapered headset bearings installed.
Front end half on
New top bushes for the rear shocks to make it compatible.
Here's a little mock up.Just waiting for my new bike lift to come.
I've got some pod filters on order + crank case vent filters.
Rejetted carbs using an online calculator (I will fine tune but as a starting point for the intake and exhaust mods)I have a slightly nicer/longer seat now which will suit my stealth appearance.
It's very hard to visualize in your head but I think it's looking more or less like how I hoped

After a bit of haggling I got an engine from a 12k mile bike (running) with warranty. I believe that is genuine, I will remove sump and cam cover to inspect+ comp test. And flush the lubrication system.
However the seller advertised it as a CB 750 nighthawk 1992 to 2003. It looks identical apart from what I couldn't see in the pictures.... It has No clutch arm!. Meaning it needs a hydraulic slave cylinder.
Also the electrics are not compatible with my loom, the cbx750 engine has loads more wires for shift lights, selector drum position etc.
I've now got to get the pulse generator sorted, source the main generator+ cover, starter motor+ cover.
The CBX has larger valves, maybe just exhaust?
Both engines have pros and cons.Right enough spending for a bit
luckily selling some old DT parts has really helped.
A bit of elbow grease and this engine really came up .... I haven't even painted it
Thinking about mounting the lights to this and using the slots for height adjustment.

@Louis-DT-WR loving the build so far. I fell in love with honda back in the late 90's after owning an nc30 for a couple of years. I must say for a "probably going to take a long time" project, (your words) lol. You have sure progressed quickly enough. At this rate you'll be riding it within the next week or two.

@markus-w thank you, I still need so many parts.
I have no experience with these bikes so i don't know how anything goes.
I need all the brake/ clutch hoses, front will have to be custom.
Levers, pedals, footrests, controls. Cables.
The biggest headache is the electrics.I can't understand why it's a push pull cable on the diagrams when the CV carbs are sprung loads on the butterfly valves. Doesn't make sense.
This engine is all new to me, I can't get any information about what year and model bike it is. Engine code is RC17E.
I'm not entirely sure if this is a breather pipe or a return pipe ..,.
Can see it on diagrams, it looks like it bridges the two sides of the cylinder assembly.
-
Wheels on.
-
@Louis-DT-WR I think it is spring loaded as well with the push pull throttle cable or how else would the throttle shut off when you let it go? Or have I miss interpreted you?
-
@markus-w it only needs a single pull cable same as the DT but the diagram shows 2 cables.
This pipe in the front of the engine must be a breather I can't see what else is would do.
